IMPROVEMENT IN Axmas.A

Specification forming part of Letters Patent No. 315479, dated January 20, 1863.

.To @ZZ whom tima/y concern:

Be it known that l, HARMON G. WEIBLING, of. Denver city, Colorado, have invented au Improvement in, Method of Lubricating Garriage-Axles, of'wliichthe following is a speci-1 v cation.

The improvement -The peculiar construction of the 'boxes or thimbles and their attachments to the axles, having alubricator at the shoulder connected with spiral grooves running the entire length of the spindle and fricton-rollers inserted in its under side.

The improvements-censiti, .in having at the shoulder of the axle an oil-chamber or founktain,j`, from whichvoil or other lubricating matter will ow through the aperturel into the spiral groove g, thus distributing the lu` bricator over the whole length of the axle from the shoulder to the point, and obviating the necessity of 'faking o ii' the wheel to oilthe spindleor axle.

The friction-rollers e e, placed in two grooves cut in the lower side of the spindle c and resting on the pipevor box b,also the friction-rollers e e in the shoulder 1L and in the burr orA nut m, the rollers in each case resting upon Babbitt metal, which will do away with much of the friction of -the ordinary thimbleske'in,

- these rollers to be-so arranged as to act inde- Y--pendentl y of each other, thereby making each to perform its own rotary motionin its own particular position.

The fastening of the box orthimble u w the hub o, andthe spindle c to the axle rIt, with vthe guttafpercha packiuga, the gutta-percha to` bedi'r'isolved to the consistency of thick' tar and thenspread upon-the surface Ot the axle k and the inner surface of the thimble or skein c. Thethimble c is then to be forced upon the axle to its proper place, aided by an irn bar insertedsinagroove in the lower side of"the axleV and extending from one end of theaxle to the other. The box b is secured inthe hub bythe same process, with the addition of the flange r, which, after the box is forced to its place, isitted onto the lower end of the box, and screwed to the hub by means of countersunk screws. By this means it will -bejmpossible'for the lubrication lused upon theaxle to penetra-te or saturate the hub o or the axle k,

and will thereby add durability to tlie wood ofthe axleor hub.- e

The `tlangesh and 'r, on the box b, y which strength is 'a'ddedto the axle and t e Oil is kept from the' end of the hub-o, also the fricv tion between the flange h and the shoulder t',-

will keep` the lubricatingr substance ina conditon to flow througb'the groove l.

The peculiar shape of thespindleA c and the box b, as shown in, the drawing, giving ,it a greater amount of strength: t

The spindle c is fastened to the axle k by means of Jthe strap 'ofjron d., running back the under side ofthe axle'k to the bolt j, or tnrough the entire length of Athe axle, the spindle c being drawntoits place and secured by means 'of the nut or vburr n, the bar d to be secured to the axle by means of kbolts running through the axle andbamor by. clasps passing over` the two, and' secured by screws and nuts.

I am aware thatrthimbles or journal-boxes.

covering the entire axle have been lknown and used, and that spiral grooves or axles are not HARMON "G. WEIBLING..
